Ju Jianting, a researcher with the Institute of Tibetan Plateau Research of the CAS, said researchers used to only have the water depth data around the lakeshore of Yamzhog Yumco, and they did not have comprehensive knowledge of the lake terrain.

Since the shape of Yamzhog Yumco is complicated, researchers decided to measure in three directions on the lake this time. They will use sonar technology to collect the depth data of the lake and draw the lake bottom isobath. The area and the water volume of the lake will also be measured and calculated with the assistance of remote sensing image, according to Ju.
